Abstract

Disclosed is a reproduction apparatus for reproducing signals from a recording medium which is capable of recording audio and video signals. The reproduction apparatus includes a memory which stores information regarding the content of recording on the recording medium; a reproduction mode selection device which selects at least three reproduction modes which include a mode for reproducing sound and image, a mode for reproducing sound only and a mode for reproducing image only; and a reproduction device which reproduces signals recorded on the recording medium with reference to the information stored in the memory according to the reproduction mode selected by the reproduction mode selection device.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A reproduction apparatus comprising: memory means comprising a plurality of memory blocks for storing information in each of said memory blocks;   determining means for determining whether the information stored in each of said memory blocks of said memory means comprises an audio signal or a video signal;   designating means for designating, free from designating a block number, reproduction of a video signal without an audio signal, the video signal being stored in said memory means; and   reproducing means operable in response to the designation by said designating means, said reproducing means comprising means for selecting only the memory block determined by said determining means to be storing a video signal, and means for reproducing information from the selected memory block.   
     
     
       2. A reproduction apparatus according to claim 1, wherein said memory means comprises a disc recording medium. 
     
     
       3. A reproduction apparatus according to claim 2, wherein said plurality of memory blocks comprise concentric circular tracks formed on the recording medium. 
     
     
       4. A reproduction apparatus according to claim 2, wherein said reproducing means further comprises a reproduction head movable in the radial direction of the recording medium and moving means for moving said reproduction head. 
     
     
       5. A reproduction apparatus according to claim 3, wherein said reproducing means further comprises means for sequentially reproducing the tracks of the recording medium from an outer track to an inner track. 
     
     
       6. A reproduction apparatus comprising: memory means comprising a plurality of memory blocks for storing information in each of said memory blocks;   determining means for determining whether the information stored in each of said memory blocks of said memory means comprises an audio signal or a video signal;   designating means for designating, free from designating a block number, reproduction of an audio signal without a video signal, the audio signal being stored in said memory means; and   reproducing means operable in response to the designation by said designation means, said reproducing means comprising means for selecting only the memory block determined by said determining means to be storing an audio signal, and means for reproducing information from the selected block.   
     
     
       7. A reproduction apparatus according to claim 6, wherein said reproducing means further comprises at least two reproduction processors for reproducing information from the selected block determined to be storing an audio signal. 
     
     
       8. A reproduction apparatus according to claim 6, wherein said memory means comprises a disc recording medium. 
     
     
       9. A reproduction apparatus according to claim 8, wherein said plurality of memory blocks comprise concentric circular tracks formed on the recording medium. 
     
     
       10. A reproduction apparatus according to claim 6, wherein said reproducing means further comprises a reproduction head movable in the radial direction of the recording medium and moving means for moving said reproduction head.
